How to reassemble HTC 10 without breaking digitizer?

I have now lost 2 digitizers to this problem. With all the guts taped up during the last step when I try reinserting the phone inside the battery cover: either the headphone jack or the charger port end don't click in and stick out. Is there a specific way to do this? If I apply pressure to push this in it cracks the digitizer.

I've see the technique where the screen remains ajar/flapped open and is the last thing to be closed in, which may prevent the digitizer from breaking but how does this phone fit together?
